Proof

Overview

Proof is a conversion optimization platform that utilizes social proof to influence website visitor behavior and increase conversion rates. Founded in 2017, the platform offers tools for displaying real-time customer activity, testimonials, and personalization elements through on-site notifications and content adjustments. The core principle behind Proof’s offerings is the psychological phenomenon of social proof, where individuals are more likely to adopt an action if they see others doing it, as detailed by marketing research from organizations such as CXL. By visually demonstrating recent purchases, sign-ups, or positive reviews, Proof aims to build trust and create a sense of urgency among prospective customers.

Proof’s product suite includes Proof Experiences (formerly Pulse), which focuses on real-time visitor activity and personalization, and Proof Campaigns (formerly Nudge), which delivers on-site notifications to highlight actions like recent purchases or testimonials. Additionally, Proof Email (formerly Email) extends these capabilities to email marketing contexts. The platform is primarily designed for marketers and businesses seeking to optimize their website performance without requiring extensive development resources for implementation. Integration typically involves embedding a JavaScript snippet on the website, which then allows the Proof platform to track visitor behavior and overlay dynamic social proof notifications.

The system is particularly well-suited for e-commerce sites, SaaS companies, and lead generation pages where demonstrating credibility and activity can directly impact conversion metrics. Proof allows users to customize the appearance and behavior of their notifications to align with brand guidelines and specific campaign objectives. This includes setting rules for when and to whom notifications are displayed, ensuring relevance and minimizing potential visitor fatigue. Compliance with data privacy regulations such as GDPR and CCPA is also a stated feature, addressing contemporary data governance requirements for businesses operating in regulated markets.

Common integrations

Proof primarily integrates with websites via a JavaScript snippet, allowing it to function across various platforms. While explicit integration guides for specific third-party tools are not extensively publicized in developer documentation, its JavaScript-based nature facilitates compatibility with most web environments and analytics platforms. The focus remains on data ingestion from the client-side for displaying social proof. However, general connectivity is implied for platforms that can host JavaScript and provide data via webhooks or similar mechanisms.

• Website Platforms: Any website capable of embedding JavaScript, including custom-built sites, WordPress, Shopify, and similar CMS or e-commerce platforms.
• Analytics Tools: Data can typically be correlated with analytics platforms like Google Analytics for comprehensive performance tracking, though direct API-level integration is not publicized.
• CRM Systems: While no direct CRM integrations are detailed publicly, data from Proof can be manually or programmatically exported and imported into CRM systems for lead enrichment.
• Marketing Automation: Similar to CRMs, data can be used to inform or trigger actions within marketing automation platforms, often requiring custom setup or data export.

Alternatives

• Fomo: Offers real-time social proof notifications with customizable designs and a focus on e-commerce conversions.
• TrustPulse: Provides social proof notifications to boost conversions, emphasizing ease of use and targeting options.
• ProveSource: Delivers social proof widgets for websites, including recent sales, visitor counts, and reviews, with varied notification types.

Getting started

Proof primarily integrates by embedding a JavaScript snippet into the <head> tag of your website. This snippet enables the platform to track visitor behavior and display social proof notifications without requiring server-side development. The process typically involves obtaining your unique snippet from the Proof dashboard after account creation and then pasting it into the designated area of your website’s HTML. For detailed instructions, refer to the Proof installation guide.

<!-- Proof Tracking Code -->
<script type="text/javascript">
  (function(p,r,o,o,f,s) {
    p[o]=p[o]||function(){(p[o].q=p[o].q||[]).push(arguments)};
    f=r.createElement('script');s=r.getElementsByTagName('script')[0];
    f.async=1;f.src='https://cdn.useproof.com/proof.min.js';
    s.parentNode.insertBefore(f,s);
  })(window,document,'_proof');

  _proof('start', { orgId: 'YOUR_ORGANIZATION_ID' }); // Replace YOUR_ORGANIZATION_ID with your actual ID
</script>
<!-- End Proof Tracking Code -->

After embedding the snippet, you would then configure your social proof campaigns and personalization rules directly within the Proof web application. The orgId is specific to your Proof account and ensures that data is correctly attributed and campaigns are delivered to your website. No further programmatic interaction via an API or SDK is typically required for standard usage, as the platform operates predominantly client-side through this embedded script.
